It's essential to figure out the right size or capacity for your room. To pick the best models in the capacity you need, you can just pick a Recommended model in that size. Or you can use the filters to select the best models based on:

Brand reliability –the brands that rate well in our member surveys.

Running costs – the better the cooling and heating efficiency score, the lower the running cost.

Noise –for the indoor and outdoor units. Where possible we show the quietest indoor fan setting.

Airflow – it's good to have a useful range of fan speeds, from quiet breeze to powerful blast.

While all the different sizes are included here, scores are not comparable between size groups. For example, it's unfair to expect the same level of efficiency from a large model as for a small one – larger models aren't as energy efficient, but they can cool or heat a much larger space.

Our review is based on data provided by manufacturers, cross-checked against the government registry database. See how we test for more details about our review method.

Size

To help you narrow your search, we class air conditioners as small (up to 4kW cooling capacity), medium (4 to 6kW) and large (over 6kW). Scores are only comparable between models in the same size category, as it's not realistic to compare the efficiency of models with very different capacities.

Type

High wall: the indoor unit is mounted high on a wall so its air flow can easily blow across the room. Floor-mounted: the indoor unit is at floor level, which may be better suit some rooms.
Cassette: the indoor unit is mounted in the ceiling. Floor/ceiling: can be mounted on either the ceiling or the floor.

Yearly running cost

Calculated based on how much each model costs to deliver 3000kWh of full cooling and 3000kWh of heating per year at maximum capacity, with the remainder of the year in standby mode (based on electricity costs of 30 cents/kWh). Standby costs add only a few dollars per year, but it may still be a good idea to unplug your air conditioner (if possible) when it's not in use for long periods.
While we've based our calculation on a reasonably typical usage, the annual running costs are only an indicative comparison. Your mileage will vary depending on your house, local climate, electricity price and how much you use the air conditioner.

Airflow score

Based on the range of airflow on the lowest to highest fan speed settings. Ideally, air conditioners should have a gentle airflow on low settings and a powerful airflow on high. The wider the range of airflows, the better the score.

Cooling efficiency score

Cooling and heating efficiency scores are based on the model's AEER (Annual Energy Efficiency Ratio) and ACOP (Annual Coefficient of Performance) – a measure of efficiency that factors in standby power consumption when the unit's not in use. Our scores are more precise than star ratings.

Human presence sensor (energy saving)

This feature detects whether anyone's in the room so the unit keeps cooling (or heating) the room. Some models also direct the air movement towards the sensed person, to focus on that area of the room and not unnecessarily use energy to cool or heat other sections.

Demand Response feature (DRED)

Demand Response Enabling Device (DRED), also known as PeakSmart. An air conditioner with this feature can be controlled remotely by participating energy companies in periods of peak electricity demand, to run in a power-saving mode. This reduces demand on the grid and should have little impact in your home. See our buying guide for more information.

Sleep mode

Sleep mode adjusts the air conditioner's output temperature and fan speed (usually in steps) so the temperature becomes more comfortable for sleeping and the air conditioner runs at lower power and more quietly.

Type

High wall: the indoor unit is mounted high on a wall so its air flow can easily blow across the room. Floor-mounted: the indoor unit is at floor level, which may be better suit some rooms.
Cassette: the indoor unit is mounted in the ceiling. Floor/ceiling: can be mounted on either the ceiling or the floor.

Status

A Similar model is identical in most aspects except for a few. This means that a majority of its test results are identical so you can reasonably expect to get the same results from the model we tested, but for those aspects which aren't identical, we'll note these as "Not Tested" in the Compare tables.

A Tested model refers to a model that is still current and available in the Australian market. You should be able to order this model through your local retailer, or find it online.

These models can't be found in retailers or online or are no longer manufactured. You may still find these models on second hand websites, or in second hand dealers. Test methods may change over time, so criteria which can't be directly compared will contain an N/A.

An Identical model is exactly that. Performance characteristics will be identical and the only difference will be something trivial such as colour, which won't have an impact on performance.

Brand reliability score

Brand reliability is based on our 2016 member survey and shows the percentage of respondents owning that brand of air conditioner who reported no problems with it in the previous 12 months. "Not available" means we didn't get enough responses to score that particular brand.

Noise indoor (dB)

Noise levels are supplied by the manufacturer. Where available, we show the noise on the quietest indoor fan setting. Noise levels are broadly comparative, but note that different manufacturers may measure these values slightly differently.
